Abstract: In a vane pump (1), the cylindrical rotor (5) of which has a single guide slot lying in an axial plane of the rotor (5) and in which the rotor (5) contacts the circumferential wall of the housing, which, in normal section, is designed as a conchoid of a circle, along a generating line, wear on the vanes (7) is reduced or avoided by the fact that opposite the rotor (5), which is mounted in projecting fashion in the housing (2), there is in the housing cover (4) opposite the bearing side a crank (10/13) mounted in freely rotatable fashion in said housing cover. This cooperates with the rotor (5) and, at its free end, has an eccentrically mounted pin (10) which engages in the longitudinal centre (15) of the vane. The centrifugal forces arising at the vane (7) during the rotation of the rotor are thereby partially absorbed by the crank (10/13). <IMAGE>

Abstract: A system for laser-ignition of explosives or the like includes a laser system (12) coupled to an optical fiber (16) for conducting light energy to a window (24) positioned at an end of the fiber remote from the laser system. An explosive charge (26) is contained within an initiator housing (18) on a side of the window remote from the adjacent fiber end. A dichroic film (30) is positioned at the window surface adjacent to the explosive charge, and is constructed to reflect light energy within one wavelength range and transmit light energy within another wavelength range. The laser system is controlled for selectively transmitting light energy at the one wavelength range to test continuity of the laser-fiber-initiator light path as a function of reflections from the dichroic film, and at the other wavelength range to ignite the explosive charge. In one embodiment of the invention, the dichroic film takes the form of a transparent disc having the film deposited thereon. The disc is of flexible resilient construction, and is sandwiched within the housing between the window surface and the explosive charge. In other embodiments of the invention, the film is formed as a coating on and integral with one of the window surfaces or on the fiber end.

Abstract: A process, an apparatus and an alloy for net-forming intricate metallic shapes are disclosed. A fixed die (30) is mounted in a forging press (20). The die (30) has a cavity (45) at least the proximal end (62) of which is open to receive a ram (55). The cavity (45) is contoured to the shape of the finished article to be forged therein, and a metallic slug (50) is receivable within the cavity (45). The ram (55) is driven into the proximal end (62) of the cavity (45) against the proximal end of the slug (50) under selected pressure and temperature and for a selected period of time. The slug (55) is thereby forged into close conformity with the contours of the cavity (45), the formation of the slug (50) being accomplished first at the distal end (52) of the cavity (45) and thereafter being progressively initiated and completed toward the proximal end (62) thereof. The foregoing process has been found to be particularly suitable for net-forming an zinc-aluminium alloy which may, if desired or required, be plated to provide the requisite hardness and sliding friction characteristics. One exemplary shape which can be net-formed by this process is a close-tolerance spool valve element.

Abstract: A patient platform (11) of a gantry assembly (9) is inserted into a scanning space (3) of a housing dome (1). Within the dome (1) around the space (3) is pro­vided an array (5) of X-ray detectors arranged circumferentially. An X-ray tube (7) is rotatably dis­posed outside the array (5). When the object (P) on the patient platform (11) is inserted into the space (3), the X-ray tube (7) irradiates X-rays in a fan shape toward the object (P). The X-ray detector array (5) performs a nutation movement during the rotation of the X-ray tube (7) so that one of the X-ray detectors on the X-ray irradiation path which is closer to the X-ray tube (7) is outside the X-ray irradiation path. In this way, the object (P) is continuously scanned in a helical man­ner with X-rays. The output of the detector array (5) is supplied to an interpolation circuit (13). The interpolation circuit (13) performs a pre-process on the output of the X-ray detector array, thereby providing projection data. The interpolation circuit (13) inter­polates a projection data at a predetermined slice (22) and having a given projection angle (φ) in accordance with two projection data at two slices located on both sides of the predetermined slice and having the given projection angle and a distances between the two slices and the predetermined slice.

Abstract: A method of sorting a mixed group of plastic articles, such as PET and PVC containers, involves individually subjecting each article to a beam of electromagnetic radiation, and detecting a change in the intensity of the beam. The measured intensity varies in a manner indicative of the crystallinity of the plastic from which the article is made, and hence identifies the type of plastic the article is made of. Each article is then sent to one of a plurality of destinations, such as recycling collection bins, according to the type of plastic. The method is particularly useful in separating PET and PVC used in containers, since these plastics are very difficult to sort by conventional methods.

Filed: 1990-05-18
Abstract: A sample applicator for use in performing immunoassays comprises a tube defining an internal lumen and having a filter matrix at one end thereof. Sample is drawn into the applicator tube, either using a vacuum bulb or an automated assay device. The sample is filtered as it enters the tube, and is again filtered as it discharged from the tube in the opposite flow direc­tion. By removing particulates from the liquid sample, assay performance can be greatly improved. The applicator may also comprise a reagent dispersed within a permeable matrix, which is useful for introducing reagent to a sample or other liquid assay component. As a liquid assay component is drawn into the applicator tube, the reagent is reconstituted by and mixed with the liquid, thereby reducing the number of steps required for the assay.

Abstract: A GPS receiver and related method for positioning on the Globe. The GPS receiver receives satellite signals in a sequential manner with a plurality of antennas, whereby any of the plurality of antennas which receives satellite signals from the maximum number of GPS satellites is selected by an antenna switching unit under the control of a control unit, a combination of GPS satellites having the smallest PDOP value or the signal strength in due order is selected by the control unit from among all of GPS satellites in contact with respective antennas when each of the antennas fails to receive satellite signals transmitted by the predetermined minimum number of GPS satellites. The related positioning method is for use with a motor vehicle-mounted GPS receiver having a plurality of receiving channels, wherein each receiving channel independently receives satellite signals from the GPS satellites in contact, a required number of GPS satellites which are currently considered to be the most suitable for positioning in view of PDOP value are selected from among all of GPS satellites in contact through each receiving channel, and thereby a GPS satellite other than the selected ones may be substituted for the obstructed GPS satellite for carrying out the positioning by making use of navigation data of the newly selected GPS satellite without any intermission.
